Link G4+ Atom

£560.00 excl tax
The Link G4+ Atom is Link's entry level ECU that blows the opposition away - half the size, all the technology! Now with more refinements for the budget conscious. Full configurability, no preset inputs / outputs. Logging, motorsport, and even closed loop fuel if an external device is added. Industry standard waterproof connectors and mounting bracket are supplied with your G4+ Atom.
Delivery date: 1-2 days

Features

 

The G4+ Atom runs the same microprocessor and firmware as our the G4+ Xtreme.

 

Designed and built to be the best "value for money" entry level ECU on the market.

 

While the G4+ Atom is entry level, the following is not compromised:

 

  • The loom (sold separately) is AVSS automotive quality cable
  • The same mounting technology as our higher level ECUs
    • A fully extruded mounting plate is included
    • Mounting hardware is completely hidden for a fully professional installation
  • Waterproof automotive plugs
  • The same tuning features as our high-end ECUs - tuning is not compromised in this "entry level" ECU
  • Full configurability, no preset input/outputs
  • Logging
  • Closed loop fuel if external devices added, e.g. WideBand Controller
  • Industry standard waterproof connectors, mounting bracket and loom, all supplied with your G4 Atom

 

    • Spec overview:

- Four injection drives

- Four ignition outputs *

- Three analog inputs (you choose, oil pressure etc.)

- Two temperature inputs (usually water and inlet air temperature)

- Two digital inputs (e.g. vehicle speed and logging switch - you choose)

- Four auxiliary outputs (e.g. fuel pump, fans, boost control, O2 heater etc.)

- One, thirty four pin, waterproof connector

- 5V out

 

* unused ignition drives can also be used as auxiliary outputs.
